The seasons due to: The Axis, Latitude

3.  Incoming radiation/insolation from
the sun heats the Earth.
 Insolation is not equal all over the
Earth’s surface.
 The amount of insolation depends on
latitude and seasons.

5.  Insolation is greater at the equator,
therefore very hot and insolation
decreases north- and southwards
towards the poles.
 Therefore heating of the earth is
affected by latitude.

6.  Heating of the Earth and it’s
atmosphere is hotter in summer as in
the winter.
 The Earth’s axis is responsible for
unequal heating and our seasons on
Earth.

8.  The Earth rotates on its own axis.
 The Earth completes one rotation on
its axis every 24 hours.
 The part of the Earth that faces the
sun and receives insolation in the 24
hours – is daytime and the other way
around.
 The earth’s Axis is tilted at 23.5˚and
causes unequal heating at the Earh’s
surface.

9.  During summer – Longer days and
more heat.
 During winter – shorter days and less
heat.

12.  Northern hemisphere is titled towards
the sun – thus daytime.
 Half of the earth facing the sun is
experiencing day the other half facing
away from the sun is experiencing
night.
 Half the Earth at the equator has day
and the other half night. Therefore at
the equator there is equal day and
night.

13. • The Southern hemisphere that has
more darkness than daylight is
experiencing winter and Northern
hemisphere summer – more daylight.
• The area between the Arctic circle and
North pole has daylight all the time –
sun never sets.
• The area between the Arctic circle and
South pole has nighttime all the time –
sun never rises.
